Lighthouses

i don't know if it's true that ratlin is the island where robert the bruce went after a battle, and it's where he saw the useless saustwell. They are said to have happened in a cave underneath the lighthouse,. There's an east lighthouse in a west lighthouse. The rathan island fog signal can be heard 20 miles away. So they've gone audio signal as well. Ye, they have a fog signal too. It's pretty cool.
